You can't make standard orange without red, as it's a primary component of the color. However, depending on the context (digital color or physical paint mixing), you might be looking for light or dark orange variations.
Understanding Color Mixing
Orange is a secondary color made by combining the primary colors red and yellow. If you want a true orange, you need red.
Alternatives and Variations if Red is Unavailable or Undesired:
While you can't get orange without red, here's what the reference is likely trying to convey regarding altering existing orange or creating similar hues:
-
Lightening Orange: If you have an orange that is too vibrant, adding white will create lighter shades of orange. This doesn't make orange, but changes an existing orange color.
-
Darkening Orange: Similarly, adding black will darken an existing orange. Again, this is a manipulation, not a creation of orange without red in the initial mixing.
Other Considerations:
-
Digital Color: In digital color spaces (like RGB or hex codes), orange is often represented by combining red, green, and blue values. You could manipulate these values to create something that visually resembles orange but might have slightly different properties (e.g., a yellowish-brown). However, technically, the "red" value would still be a component.
-
Misinterpretation: It's possible the questioner meant something different entirely. Perhaps they are looking for analogous colors to orange or a specific shade attainable through unusual color combinations. Without further context, a definitive answer beyond the fundamental mixing of red and yellow to achieve orange is challenging.
In conclusion, the core principle stands: true orange requires red. Alterations can be made to orange after its creation by adding white (lightening) or black (darkening).
